摘要 针对均衡异常数据,比较分析了连续曲率张力样条方法、最小曲率方法和Shepard方法,结果表明张力样条方法解的全局效果较好。 The methods of continuous curvature splines in tension, minimum curvature and Shepard＇s method were compared and analyzed using isostatic anomaly data. The results show that continuous curvature splines in tension method has better global properties, higher precision and good result of interpolation or extrapolation in poorly constrained regions.
